SPECIFICATION forming' part of Letters Patent No. 732,490, dated June 30, 1903.

Appncatiou inea July 23,1902'. sain No. 116,636. (No man.)

.T0 all whom t 11o/ty concern:

Be it known that I, RAYMOND DEE YORK, a citizen of the United States, and a resident of Portsmouth, Ohio, have invented certain new and useful Improvements in Rolling- Mills, of which the following is a specification accompanied by drawings.

My improvement relates to rollingmills having in combination main rolls arranged one above another and side rolls opposite the adjacent portions of the main rolls.

' My improvement particularly relates to means whereby antifriotion-rollers may be more advantageously employed for supporting side rolls in a rolling-mill.

In the accompanying drawings, Figure l is a vertical sectional elevation of the principal parts ofa rolling-'mill embodying myimprovement. Fig. 2 is a horizontal section, upon a larger scale, showing the bearings for one of the side rolls. Fig. 3 is a vertical section of the parts shown in Fig. 2 at the plane of the dotted line 3 3, Fig. 2. Fig. 4 is a vertical section of the parts shown in Fig. 2 at the plane ofthe dotted line 4 4, Fig. 2. Fig. 5 is a perspective view of a toothed wheel comprised in my improvement. Fig. 6 is aview similar to Fig. 4, illustrating a modification. Fig. 7 is a similar View to Fig. 4, illustrating another modification. Fig. 8 is a detailvertical sectional View perpendicular to the axis of the rolls, showing the relation of the journals of the rolls to the supporting piece, which straddles one of the journals.

Similar letters of reference designate corresponding parts in all the igures.

A A2 designate the main rolls of a rollingmill, the lower roll A being preferably arranged in fixed bearings and the upper roll A2 in vertically-adj ustable bearings arranged in housings b in a framework B and adjusted by screws C and hydraulic engines D, said screws being arranged to press downward and the hydraulic engines to move upward the u pper roll A2.

E' E2 designate side rolls. -They are Without externally-projecting tru nnions, and consequently provide for a close relation of the journals of the rolls A' A2, and so enable the bodies of the rolls A' A2 to be made smaller in diameter than otherwise they would have to be. In the lower end of each of the rolls E E2 is a cylindrical cavity e, and into such cavity projects a cylindric bossor bearing e', extending, as here shown, from a supportingpiece E3, which straddles the adjacent journal of the lower roll A. Each of these rolls E E2 may be lubricated through a passage extending downwardly from its upper end.

In addition to the supports already de` scribed for the rolls E' E2 there are supports consisting of a series of antifriction-rollers.

In Figs. l, 2, 3, and 4 there is shown a series of 'vertical rollers G, arranged in a recess of lune or crescent shaped outline. The inner boundary of this recess is a lune or crescent shaped backing-piece H and the outside boundary is a confining piece or shell H2. These are shown as comprised in a casing. Each backing-piece H is shown as being formed integral with a supporting-piece E3 and a top piece E4, and this is advantageous for economizing space. I have showneach confining piece or shell H2 as made separately and secured by screws to a contiguous supporting-piece E3. The backing-piece H at that-side which is opposite a side roll E' or E2 is advantageously provided with a detachable facing-piece h, made of suitably hard material and attached by screws h', so as to be readily capable of removal. Such facingpiece hwill be opposite the roll E or E2, and the rollers G intermediate of these two parts serve to support the adjacent roll E or E2 with a minimum of friction during the rolling operation. The rollers are moved by the roll E or E2 around the lune or crescent shaped recess. Preferably I employ some means for presenting the antifriction-rollers in proper position for coperation with the roll which they are to support, and such means may be advantageously arranged at the ends of the lune or crescent shaped recess. These means should conduce to secu re upright positions of the antifriction-rollers while the latter are traveling concentrically with the rolliwhich theysupport. Suchpresentingmeansarehere shown as consisting of toothed wheels H2 and H4, having between their teeth spaces IOO . In Fig. 6 I have shown a number of short l roll, of a series of antifriction-rollers travelrollers A3, arranged in superimposed grooves formed in the backing-piece and its facingpiece instead of single long rollers. Vith these rollers the toothed wheels H3 H4 are less import-ant and may be omitted.

In Fig. 7 the part-s are very similar to those in Fig. 6, but the rollers Gr2 are round or globular instead of cylindrical. Instead of being wholly supported by grooves in the backing-piece and facing-piece they may be more or less supported by being superimposed directly one upon another.

It will be seen that by this improvementin all the examples which I have given vertical side rolls are supported by a series of antifriction-rollers moving around the side rolls concentrically in an arc of sufficient length to afford a bearing both at the backs and laterally of the side rolls, and hence against all forces to which the side rolls will be subjected, and that all of said antifriction-rollers travel in a circuit which is wholly beyond the side rolls.

What I do claim as my invention, and desire to secure by Letters Patent, is-

l. In a rolling-mill, the combination with a vertical roll, of a series of antifriclion-rollers traveling in a recess part of which is concentric with the roll and the remainder of which is wholly beyond the roll, the said antifriction-rollers in the concentric portion of the recess forming an arc of sufficient length to afford a bearing both at the back of the roll and laterally thereof.

2. In a rolling-mill, the combination with a vertical roll, of a series of antifriction-rollers traveling in a recess, part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, the said antifriction-rollers in the concentric portion of the recess forming an arc of suliicient length to afford a bearing both at the back of the roll and laterally thereof, that wall of the recess which is concentric with the roll, being provided with a detachable facing-piece.

3. In arolling-mill, the combination with a vertical roll, of a series of antifriction-rollers traveling in a recess, part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, and bodily-immovable toothed or recessed. wheels facilitating the travel of the rollers.

4. In a rolling-mill, the combination with a vertical roll, of a series of antifriction-rollers traveling in a recess, part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, and bodily-immovable means for assuring the travel of the rollers in proper position for cooperation with the roll.

5. In a rolling-mill, the combination with a ing in a lune or crescent shaped recess, part of which is concentric, and the remainder of Which is wholly beyond the roll, and toothed or recessed wheels at the points of the lune or crescent shaped recess facilitating the travel of the rollers at those points.

6. In a rolling-mill, the combination with a vertical roll, of a series of antifriction-rollers traveling in a lune or crescent shaped recess, part of which is concentric, and the remainder of which is wholly beyond the roll, the antifriction-rollers in the concentric portion of the recess forming an arc of sufficient length to aord a bearing both at the back of the roll and laterally thereof.

7. In a rolling-mill, the combination with a vertical roll, of a backing-piece and a confining-piece,one of which is provided with a n umber of superimposed grooves formed therein said pieces forming a recess between them part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, and a number of superimposed antifriction-rollers traveling in the said grooves and forming a bearing for the roll.

8. In a rolling-mill, the combination of a vertical roll having in one end a cylindric cavity, a boss or bearing entering said cavity, and a Series of antifriction-rollers traveling in a recess, part of which is concentric with the roll, and the remainder of which is wholly beyond the roll.

9. In a rolling-mill, the combination with a vertical roll, of a backing-piece and a confining-piece forming a recess between the same, a part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, and a series of antifriction-rollers traveling in said recess, and forming the bearing of the roll, the confining-piece being so constructed and arranged as to be out of contact with the roll, whereby the bearing is afforded solely by the antifriction-rollers.

l0. In a rolling-mill, the combination with a vertical roll, of a backing-piece and a supporting-piece formed in one integral structure, a confining-piece secured to the supporting-piece, and forming with the supporting-piece and backing-piece a recess part of which is concentric with the roll, and the remainder of which is wholly beyond the roll, and a series of antifriction-rollers traveling in said recess and sustaining the roll.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
